That sounds beyond retarded. Different nations are differently affected by the spread and have to figure out how to best handle their own situation, even different regions within each country are having different situations. Having EU officials make unilateral decisions for everyone is unfathomably stupid, these decisions must be made by local regional governments.
EU’s only role in this should be to help those regions that are hardest hit and have a hard time providing enough care and economically survive the quarantine.
